JOHN GEORGE MORITZ, OF GRAFTON, WEST VIRGINIA.

APPARATUS son roaMnt'e VASES.

To all whom it may concern:

Be it known that 1, JOHN GEoRon Momrz, a citizen of the United States of America, residing at Grafton, in the county of Taylor and State of West Virginia, have invented certain ne and useful Improvements in Apparatus for Forming Vases, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to an apparatus for forming vases and the primary object of the invention is to provide means for holding and the same time crimping the top of a ass vase or like article while the same is being drawn into the desired shape.

In the drawings: Figure 1 is a front ele ration of a machine embodying the invention, with the drawing snap removed. Fig. is a side elevation of the same. Fig. 3 is a view partly in elevation and partly in vertical section of the machine. Fig. at is a sectional view of the air-blast pipe and its valve. Fig. 5 is a detail sectional view illustrating the means for holding and crimping the top of the vase. Fig. 6 is a side elevation showing a molded vase in position and the two-part snap connected therewith for shaping the vase. Fig. 7 is a detail view partly in elevation and partly in section of a two-part snap and its handle or stem, and Fig. 8 is a detail perspective view of the two-part snap.

The machine embodies a platform 1, which carries the different parts of the mechanism, and, for convenience sake, is preferably supported by wheels 2 mounted on axles 3 and 1, so that the machine or apparatus can be moved from place to place in the factory, as may be desired.

A standard 5 rises from the platform 1, braces 6 being provided for giving rigidity to the standard, and upon the latter are adjustably-secured bifurcated arms 7 having bearings for shafts 8 upon which are mounted grooved guide pulleys or wheels 9.

Upon the platform 1 is mounted a former 10 cooperating with clamps 11 and 12 provided with scalloped jaws 18 and pivotally secured to brackets 1 1 projecting from the platform 1.

The clamps 11 and 12 are each provided with a rod 15 carrying a weight 16 at its outer end, said clamps being connected by rods 17 to a bar 18 adapted to be operated. by a treadle 19 fulcrumed on the axle 3.

Specification of Letters Patent.

Application filed December 5, 1907.

Patented Jan. 12, 1909.

Serial No. 405,171.

To cool the vase I employ an air pipe 20 adapted to be attached to a suitable air supply (not shown), the passage of air through the pipe 20 being controlled by a valve 21 attached to a lever 22, and normally held closed by a coil sprin 23.

A gage 24 is adjustably supported on a rod 25 secured to the platform 1, said gage being employed as a guide to the operator in the drawing of the vase.

To draw the vase into elongated form, I employ a two-part clamp 25 connected to a hollow stem or handle 26, which latter, in operation, rests against and is guided by the pulleys or wheels 9. This snap is of the usual form employed in glass factories, and requires no detail description, as the construction of the same per se forms no part of my invention.

The operation of the machine is as fol lows: The molded vase 23 is heated and is then inverted so that its top rests on the former 10, when the treadle 19 is operated so as to engage the clamps 11 and 12 with the vase, as seen in Fig. 5, the former 1O andthe clamps 11 and 12 crimping the top of the vase. The two-part snap 25 is then engaged with the base of the vase, and the operator pulls upwardly on the handle 26 of the snap until the vase has been drawn into the desired shape or form, the pulleys9 acting as guides for the handle of the snap and preventing the latter moving out of vertical alinement with the vase. As soon as the desired form has been imparted to the vase, the operator opens valve 21 to allow the air to pass to the vase through pipe 20, and cool the vase, after which the snap is removed, the operator relieves the pressure on the treadle 19, the weights 16 open the clamps 11 and 12, and the finished vase is removed from the former 10.

I would have it understood that the invention includes all such modifications and variations in the details of construction, as may fall within the scope of the invention claimed.

Having now described my invention what I claim as new, is

1. In an apparatus for the manufacturing of glass vases, the combination with a platform, a standard supported thereon, and guide wheels carried by said standard, of a former mounted on said platform, weightedclamps pivot-ally-mounted on said platform.

1 and cooperating with said former, means for operating said clamps to move the same towards the former and engage one end of a vase, and a snap to engage the other end of the vase and having ahandle engaging and guided by said guide-Wheels.

2. In an apparatusfor the manufacture of vases, the combination with a platform, a standard supported thereon, guide-wheels adjustably-secured to said standard, a rod risingv from theplatform, and a gage adjustably-secured to said rod, of a'former on said platform, weighted-clamps pivoted on the platform and cooperating with said former toashape and hold one end of a vase, and a snap for engagement with the other enchof the vase toelongate and shape the latter,\said-snap having a handle engaging said guide wheels and guided thereby during the movement of thesnap.

3. In an apparatusfor shaping vases, the combination with a suitably mounted former, and means cooperating with said former for shaping the top of the vase, of a 'sn'ap to engage the base of the vase and havinga handle, andmeans'supported above the former in line therewith to be engaged by saidhandle for guiding the snap as-the latter is moved away from the former.

V former, and means cooperating with said former for shaping the top of the vase, of a snap to engage the base of the vase and having a handle, means supported above the former in line therewith to be engaged by said handle for guiding the sna as the latter is moved awayfrom the lb means for supplying a blast of air to the completed vase to cool the same. a

5. In an apparatus for shaping vases, the combination with a suitably mounted former, weighted clamps cooperating" with said former for shaping thetop of the vase, guide wheels supported above'the former in line therewith, and a-snap to engage the base of the vase and having a handle engaging and guided by said wheels, and means for supplying a blast of air to the completed vase to cool'the same.

In testimony whereof I aflix my signature in the presence of two witnesses.
